Note:
1. Connect VASEL to V- will disable “A” and enable “V” units on LCD panel, so in other modes, this pin
must keep floating.
2. Connect VBAR to V- will disable the “µ2” / ”m2” symbol on LCD panel, so in the mV range of voltage
measurement, this pin must keep floating.
3. In DC current modes for clampmeter, ES51967 provides Zero function for offset removing.
4. The typical connection of input terminal is as the schematic below:
*The voltage results from induced current flows through a load resistor. Its input range is up to 3.3Vrms.
